Diplomatic tensions have flared since the head of the African Union Commission, Moussa Faki Mahamat, met last week with a political adviser to the paramilitary Rapid Support Forces (RSF), prompting rebuke from Burhan's government.
The brutal war since April 15 between the army and the RSF has killed "nearly 7,500" people, according to a Friday report by the Armed Conflict Location & Event Data (ACLED) project which noted the toll was "a conservative estimate".
ACLED as well as activists and aid groups on the ground have repeatedly warned that casualty figures out of Sudan are underreported as fighting hampers access to many areas and the warring sides do not disclose deaths among their ranks.
Much of the violence has been concentrated around the capital Khartoum and the western region of Darfur, where witnesses again reported clashes on Saturday between army forces and the RSF on the outskirts of El Fasher, the North Darfur state capital.
Diplomatic efforts to end the fighting between the forces of Burhan and his former deputy, RSF commander Mohamed Hamdan Daglo, have repeatedly floundered.
Multiple truces brokered by the United States and Saudi Arabia in the early stages of the war had been systematically violated before the two mediators adjourned talks in June.
More recently, some moves by the army chief including trips to Egypt, South Sudan and Qatar have signalled a potential return to diplomacy.
But in a speech Saturday rallying troops in the southern state of Blue Nile, Burhan seemed to shun regional mediation efforts.
"If this is your approach, we don't need your help," the army chief said of the African Union, referring to Faki's recent meeting with the RSF adviser, Youssef Ezzat.
The Burhan-controlled foreign ministry has called the meeting "a dangerous precedent" and "a clear violation" of the continental bloc's norms, saying it "should hold no place for rebel movements and criminal terrorist militias".
Mohamed El Hacen Lebatt, a spokesman for the AU Commission, said in a statement Thursday the organisation was committed to interacting "with all parties".
Lebatt noted that no Sudanese party had expressed "any reservation" when "the same approach" was adopted by other international actors.
The AU suspended Sudan's membership in 2021 after Burhan and Daglo together led a coup that derailed a transition to civilian rule following the ouster of longtime strongman Omar al-Bashir.
Speaking in the Blue Nile city of Al-Damazin on Saturday, Burhan also took East African bloc IGAD to task, after his administration has repeatedly accused mediation coordinator Kenya of siding with the RSF.
IGAD "has deviated from its course", Burhan said. "We Sudanese can solve our problems ourselves."
